Thisconfuses Session.IdleTime with Session.ExpirationTime. Windows can createadditional authenticated sessions on an existing connection, so deletingthe older session invalidates its tree connects and makes mapped drivesfail with STATUS_NETWORK_NAME_DELETED.\nThe session expiration rules require the server to change a valid sessionto expired only after its credential expiration time passes. A valid orexpired session otherwise keeps its connection from being scavenged.Connections that have not negotiated a dialect, have no sessions, or haveonly InProgress sessions are disconnected after an implementation-specifictimeout. Use the Windows-compatible 45 second value and run the expirationcheck periodically for both TCP and SMB Direct.\nKeep zero as an infinite credential expiration time, and count eachValid-to-Expired transition. Set expired sessions to InProgress when theyreauthenticate. If authentication fails, remove the session from theglobal and per-connection tables immediately, including SMB3 multichannelconnections.\nRetain protection against abandoned SessionId-zero exchanges by allowingonly one InProgress authentication per connection. Additional exchangesfail with STATUS_INSUFFICIENT_RESOURCES, and stale InProgress sessions arereaped after the same 45 second setup timeout. This bounds the originalunauthenticated memory-exhaustion path without evicting establishedsessions.\nhttps://www.cve.org/CVERecord?id=CVE-2026-98420https://git.kernel.org/stable/c/c99ea7855124ca1428a1e59c2b4590aaef34eacfhttps://git.kernel.org/stable/c/d7fd1f98607f2cd358e583f9548bdf0173090a86#kernel #Linux#CVE_2026_98420#bot", "url": "https://infosec.exchange/users/cve/statuses/117440743823658667"}, {"timestamp": "2026-10-16T06:05:38.341Z", "date_only": false, "value": "2026-10-16T06:05:38.341008Z", "kind": "milestone", "label": "Published", "source": "osv_bellsoft \u00b7 BELL-CVE-2026-98420", "record": "BELL-CVE-2026-98420", "field": "published"}, {"timestamp": "2026-10-16T06:42:47.644Z", "date_only": false, "value": "2026-10-16T06:42:47.644099Z", "kind": "other", "label": "Updated", "source": "osv_bellsoft \u00b7 BELL-CVE-2026-98420", "record": "BELL-CVE-2026-98420", "field": "modified"}]}
